Abstract

An electric heater having a housing with an air inlet area, an air outlet area, an electric heating element disposed between the inlet area and outlet area, a fan that moves air through the heater, a first high-temperature limit switch mounted on the housing in the air inlet area, and a second high-temperature limit switch mounted on housing in the air outlet area, the first and second switches being electrically connected in series with each other and to the heating element so as to disconnect power to the heating element when either switch is tripped.
